pthread_attr_getdetachstate(3C) Standard C Library Functions pthread_attr_getdetachstate(3C)
NAME
pthread_attr_getdetachstate, pthread_attr_setdetachstate - get or set detachstate attribute
SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ]
#include <pthread.h>
int pthread_attr_setdetachstate(pthread_attr_t *attr,
int detachstate);
int pthread_attr_getdetachstate(const pthread_attr_t *attr,
int *detachstate);
DESCRIPTION
The detachstate attribute controls whether the thread is created in a detached state. If the thread is created detached, then use of the
ID of the newly created thread by the pthread_detach() or pthread_join() function is an error.
The pthread_attr_setdetachstate() and pthread_attr_getdetachstate(), respectively, set and get the detachstate attribute in the attr
object.
The detachstate can be set to either PTHREAD_CREATE_DETACHED or PTHREAD_CREATE_JOINABLE. A value of PTHREAD_CREATE_DETACHED causes all
threads created with attr to be in the detached state, whereas using a value of PTHREAD_CREATE_JOINABLE causes all threads created with
attr to be in the joinable state. The default value of the detachstate attribute is PTHREAD_CREATE_JOINABLE.
RETURN VALUES
Upon successful completion, pthread_attr_setdetachstate() and pthread_attr_getdetachstate() return a value of 0. Otherwise, an error num-
ber is returned to indicate the error.
The pthread_attr_getdetachstate() function stores the value of the detachstate attribute in detachstate if successful.
ERRORS
The pthread_attr_setdetachstate() or pthread_attr_getdetachstate() functions may fail if:
EINVAL attr or detachstate is invalid.
